44 claims.l (c1. 19a-'6) This invention'relates to chutes. -An object of the invention is to provide a chute which may be used for any and all lpurposes requiring the use of a chute. K-

An object of the present invention is also 'to provide an improved extensible chute' wherein the sections thereof telescope to reduce the chute to such a size as to require but small storage space when not in use, or whichchute can be extended to the desired length in accordance with the requirements as to length, and as determined by the distance between the point of location of the i material and the point to which the material is to be directed through the medium or the chute. A further object of the invention is to provide y a chute composed of telescoping sectionsand characterized by having the: sections tapered in such a manner that the chute may be extended in a straight line or at an angle as found desirable.

The invention, together with its objects and advantages will be best understood from a study of the following description taken in connection with the accompanying drawings, wherein:

Figure l is a top plan view of the improved chute, the same being shown extended in a straight line.

Fig. 2 is a side elevational View of the chute.

Fig. 3 is an elevational view of the chute at the inner end thereof.

Fig. 4 is an end elevational View of the section of the chute forming the discharge end of the chute, and

Fig. 5 is a detail sectional view taken substantially on the line 5-5 of Fig. 1.

Referring to the drawings by reference numerals, it will be seen that the improved chute comprises a plurality of telescoping sections including an inlet section. 5 a discharge end section 6, and any desired number of intermediate sections 1. Y

Each of the sections 5, E, and l have flange sides and taper from the rear to the front, and these sections are secured together bymeans of slots 8 formed in the flanges 9 of the sides lil of the respective sections 5 and l, and the fixed rivets l I provided at one end ofthe flanges of all Y of the sections, with the exception of the section 5 and extending through the slots 8 of the sections 5 and 1, as clearly shown.

To permit a complete telescoping` of the sections for the full length of the respective sections, the flanges 9 of sections 5 and 1 have the front ends of said sections provided with bells o1' struck-up portions I2 formed by pressing portions of the'flangesupwardly'out of the plane of the flanges, the bells serving to accommodate the heads of the frivets, in a manner to permit the heads of the rivets'fof each section to start under the flanges of the next preceding section when the sections are telescoped for reducing the length of' the chute. 1t will be apparent that when the heads of the rivets are thus placed under the fluted opinen-equipped ends of the Y anges',` there is nothing' to prevent movement of the'severalsections' asrequired to telescope said sections.

The section 5 at the front or intake end of the chute is flared at its. intake asl at I3 and is reinforced thru the medium of an angle bar I4 that extends across the bottom of the chute section and up alongside the sides of said chute section being riveted to the bottom and sides or otherwise positively secured thereto.

Intermediate its ends the angle bar lil is provided with spaced notches l5 as shown in Fig. 3, through the medium of which the chute may be suspended at its intake end from a wagon box or the like through the medium of hooks, chain, or similar means.

Also to prevent creeping of the chute at the discharge end thereof, there are suitably secured to the under side of the bottom of the section 6 of the chute, straps I6 having downturned ends Il forming cleats to engage the ground to provide, as it were, an anchor for the discharge end section 6 of the chute. It will be further appreciated that with the cleats ll' engaged with the ground, the several sections of the chute will be retained at the desired position oi' adjustment, thereby preventing accidental telescoping of the sections or unintended extension of the chute.

It will be further noted that the flanges 9 of Y each section taper longitudinally in proportion to the amount of taper of the respective chute sections. This will permit the slots 8 to remain parallel at all points, leaving sufficient stock to retain the proper supporting strength in the anges.

From the above it Will be seen that I have provided a strong, durable chute composed of telescoping sections and which can be lengthened or shortened as found desirable; and which when the sections are completely telescoped, will require but comparatively small storage space.

Having thus described the invention, what is claimed as new is:-

1. An extensible chute consisting of a plurality of telescoping trough sections having tapering sides, the sides of said sections being provided with lateral outstanding tapering flanges having longitudinal slots formed therein, and rivets secured to the flanges of the respective sections and engaging in the slots of the flanges of the next succeeding section for connecting the sections together, and the flanges of each section at one end thereof having struck-up portions accommodating the rivets of the next preceding section, when the sections arertelescoped.

2. An extensible chute consisting of a plurality of telescoping trough sections having tapering sides, the sides of said sections being provided With lateral outstanding flanges 'having longitudinal slots formed therein, rivets Vsecuredto the flanges of the respective sections and engaging in the slots of the flanges ofthe next succeeding section for connecting the sections to` gether, and the anges of the respective sections having bells at one end thereof to accommodate the heads of the rivets of the next preceding section.

3. An extensible chute consisting of a plurality of telescoping trough sections having tapering sides, the sides of said sections being provided with lateral outstanding flanges having longitudinal slots formed therein, rivets secured tothe flanges of the respective sections and engaging in the slots of the anges of the next succeeding section for connecting the sections together, the flanges of the respective sections having bells at `the flanges of the respective sections and engaging in the slots of the anges of the next succeed- Ving section for connecting the sections together, Vthe flanges of the respective sections having bells at one'end thereof to accommodate the heads of the rivets atr the next preceding section, said sections including an intake section having a flared intake end, a reinforcing bar secured to said' flared intake endand extending across the bottom and sides of the last-mentioned section at the mentioned end thereof, and said reinforcing bar being provided With notches at an-intermediate portion thereof for engagement with at- Y taching means for anchoring said intake end of the chute to a support, and said chute also in'- cluding a discharge section, andanti-creeping devices on the under side of the discharge section ofthe chute, as and for the purpose specified.
